Description
Przedmiotem wynalazku jest sposób wzbogacania mieszanin mineralnych zawierajacych mineraly siarczkowe zwlaszcza siarczkowych rud miedzi.The subject of the invention is a process for the fortification of mineral mixtures containing minerals sulphide, especially sulphide copper ores.
Opis dotychczasowego stanu. Stosowany obecnie proces przeróbki rud miedzi jest nastepujacy. Material wejsciowy (ruda) poddany jest kolejno procesowi kruszenia i mielenia. Zmielony material stanowi nadawe do procesu flotacji pianowej.Description of the current state. The currently used copper ore processing process is as follows. Material the input (ore) is successively crushed and milled. The ground material is suitable for the froth flotation process.
W procesie flotacji pianowej stosuje sie obecnie dwa odczynniki flotacyjne etyloksantogenian sodowy i alkohol dwuacetalowy + tlenek mezytylu. Z flotacji pianowej otrzymywany jest koncentrat siarczkowy i odpad poflotacyjny. W dotychczasowej technologii, w procesie flotacji pianowej nastepuje wzbogacenie tylko duzych i srednich ziarn siarczków miedzi. Ziarna drobne nie sa flotowane i prawie w calosci przechodza do odpadów koncowych.Two flotation reagents, sodium ethylxanthate, are currently used in the froth flotation process and diacetal alcohol + mesityl oxide. Sulphide concentrate and waste are obtained from foam flotation post-flotation. In the existing technology, only the large ones are enriched in the froth flotation process and medium grains of copper sulfides. The fines are not floated and almost entirely waste final.
Istota wynalazku. Istota wynalazku polega na zastosowaniu metody opartej na procesie selektywnej flokulacji. Zgodnie z wynalazkiem jako flokulant stosuje sie sól sodowa kwasu celulozowo-ksantogenianowego (wiskoza), która otrzymuje sie jako pólprodukt w przemysle wlókien sztucznych.The essence of the invention. The essence of the invention consists in the use of a method based on a selective process flocculation. According to the invention, the sodium salt of cellulose-xanthate acid is used as the flocculant (viscose), which is obtained as an intermediate in the synthetic fibers industry.
Zastosowanie metody opartej na procesie selektywnej flokulacji z zastosowaniem produktów przemyslowych zawierajacych sól sodowa kwasu celulozowo-ksantogenianowego jako odczynnika flokulacyjnego, pozwala na: — odzyskanie drobnych ziarn mineralów siarczkowych — zastapienie obecnie stosowanych odczynników flotacyjnych przez odczynniki flokulacyjne.Application of the method based on the process of selective flocculation with the use of products industrial products containing sodium salt of cellulose-xanthate acid as a reagent flocculation, allows for: - recovery of fine grains of sulphide minerals - replacement of the currently used flotation reagents by flocculation reagents.
Przyklad realizacji wynalazku. W celu zastosowania metody opartej na procesie selektywnej flokulacji, nalezy bedacy wodna zawiesina, drobno zmielony (1 :30 fi) material wyjsciowy tj. rude miedzi, pólprodukt z flotacji lub odparty poflotacyjnie, zdyspergowac przy uzyciu polifosforanu sodu lub szkla wodnego.An embodiment of the invention. In order to apply the method based on the selective flocculation process, should be an aqueous suspension, finely ground (1: 30 phi) starting material, i.e. copper ore, semi-finished product from flotation or post-flotation, disperse with sodium polyphosphate or water glass.
Do tego celu mozna równiez stosowac odczynniki zagraniczne typu Dispex 115 lub Dispex N-40.For this purpose, foreign reagents such as Dispex 115 or Dispex N-40 can also be used.
Odczynnik dyspergujacy dodawany jest do zawiesiny w postaci roztworu wodnego. Na otrzymana w ten sposób2 93 247 stabilna zawiesine dziala sie odczynnikiem flokulacyjnym o dzialaniu selektywnym. Warunki takie spelniaja pólprodukty przemyslu wlókien sztucznych zwane ,,ksantatem" lub „wiskoza". Odczynnik flokulacyjny oddawany jest w ilosci 3—5 kg na 1 tone suchego materialu wejsciowego jako 1—2% zasadowy roztwór wodny.The dispersing reagent is added to the suspension as an aqueous solution. Thus obtained 2 93 247 the stable suspension works with a flocculating reagent with a selective action. Such conditions are met semi-finished products of the man-made fiber industry called "xanthate" or "viscose". Flocculation reagent it is given at 3 to 5 kg per 1 ton of dry input material as a 1 to 2% alkaline aqueous solution.
W wyniku dzialania odczynnika flokulacyjnego ze stabilnej zawiesiny, pozostajacej w stanie spoczynku, wytraca sie osad w postaci klaczków (flokól). Osad stanowi produkt wzbogacany w mineraly siarczkowe. Oddzielenie osadu od pozostalej czesci zawiesiny pozwala otrzymac bogaty koncentrat siarczkowy.As a result of the action of the flocculation reagent, the stable suspension in a rest state loses a sediment in the form of filly (flockery). The sediment is a product enriched with sulphide minerals. Separation sediment from the remainder of the suspension allows to obtain a rich sulphide concentrate.
